We live in an area with very hard water, and even with an excellent water softening system, it is not enough (Too many hard particles). This product works great at getting out stains even in difficult water conditions. I have a front load washer and really love the convenience of being able to toss the little package into the washer with the cloths and hit the button. No measureing of messy liquids or loose powders. So far this product is working great!!!

Used the GrabGreen laundry detergent, and found them so good, so decided to give these a go.
These are amazingly good too.
They get whites SO white, better than anything other product I've come across.
Also tried mixing one pod with water, & rubbing into drier in stain in carpet,..and it worked great, took stain out.
Will continue to use, and will buy them again from iHerb.
